TYPEWRI'IING Application led July 25,

This invention relates toimprovements in bookkeepingdevices,'attachablefor use upon the carriage ofan Underwood standardbookkeeping machine. In such machines entries are made on individualcards or memorandum-sheets, and copies of 'such entries are also kept ormade upon proof or record'sheets, as usual. A single ventry is made atany particulartime upon each -memorandum-sheet, while the proof orrecordfs'heet is retained in the machine and thereafter all the entriesare ymade thereon in sequence until the sheet is full.

One of the lobjects of the present invention is to provid-e a simple,efficient and in` expensive attachment for the type of theaforementioned machine vwhich will effectivelyposition relatively to therotatable platen of kthe 'machine and longitudinallyY thereof, atypewriter-ribbon which is auxiliary to the usual and maintypewriterribbon found in such machine, and in such a manner that thcauxiliary-ribbon is suitably divided into two stretches, one of which ispositionably adjacent the printing line ofr the machine, and the otherof which is arranged out-of longitudinal alignment so as tobegspaced`vertically from the other stretch and `fromsaid printing line.

This expedient `finds particular application in'all cases where it isdesirable tov maintain in proper feeding relation, upon the platen of atypewriting machine, a plurality of sheets; saytwo sheets, oneoverlapping the other andfbeing of a greater width in conjunctiontherewith, so as to'leave a margin upon `the wid-er sheet. Thisarrangement of sheets is serviceable toV allow inscriptions to be typed,line by line, upon the relatively narrower sheet, so'as to assure,through the medium of carbon-sheets, or the-like. that those sameimpressions be produced simultaneously upon the wider sheet; and withoutshifting one sheet with respect to the other sheet` and while the platen.and carriage continue to make their rectilinear traverse, it ispossible to type inscriptions upon the margin of the wider sheet whichflanks the narrower sheet, so that these inscriptions may be in linewith the-line of inscriptions already typed upon thenarrower sheet,while the carriage and platen are finishing the same traverse across themachine. 1 Y Y y vThe present invention interleaves between 1924.serial' No.y 72eme'. y

the twoy sheets, notv carbon-sheets, but a typewriter-ribbon whichextends completely across the longitudinal axis of the platen,projecting beyondthe effectivel width of the narrower sheet and*extending completely across the margin of the wider-sheet by reasonofthe manner in which thev two stretches of this typew'riter-ribbon,already Y explained, are arranged in vertically spaced'- apart relation.It will readily be yseeny that one of these stretches is v allotted tothe' narrower lsheet extending'completely across the same, and the otherstretch of the same ribbon is allotted exclusively to they marginalportion of the wider sheet, so 'as -to allow the first stretch tobelocated at the printing line of the machine andthe other stretch in aposition spaced away therefrom, thereby exposing to View of the typistVany inscriptions that may have been typed` upon the marginalportion;ofthe wider. sheet which are located alsoattheprinting line of themachine. It will be understoodthat the main typewriter-ribbon isarranged .so y

as to always come into yprinting-line position, sothat upon theimpinging of the usual type-bar therewith at all points upon .itssurface co-extensively with thefxfull length of the platen impressionsare made at the printing linev across the narrower sheet, which arereproduced, owing to the Y impinging of the same type-bars with theauxiliary ribbon, upon the wider sheet and impressionsv are also-produced, directly, through the'main ribbon, upon the marginal portionof the Iwider sheet at the printing line (as contradistinguished frombeing reproduced), because in this region the main ribbon does notoverlife and is'not-in `longi-V controlled, in operation, by the`line-spacing A y16 of said frame.

mechanism for urging the auxiliary ribbon along in movable relation withrespect to the fixed point of engagement of each typebar relatively tothe traveling platen. By

means of the present invention any portion of the length of theauxiliary ribbon may be instantly offsetwith relation to another portionwithin the Zone of the printing operation, so that, while oneportionextends along the printing line, the other portion is spacedtherebeyond;"likewise itis possible'to dispose and position a givenlength of the auxiliaryribbon so that it extends completely across thelength of the platen, and is locate-d at the printing line or beyondptheprinting line, as exigencies may dictate, and when it is desired'toshift, insert or remove either or both of the sheets held against theplaten of the machine, the present invention is arranged to be manuallylifted with its auxiliary ribbon out of contact with the sheets, so asto permit this action to take placeconveniently.

Other features and advantages will hereinafter appear.

Referring to the drawings which are merely illustrative of the presentinvention, 10 and 11 designate the side members or pieces of the usualplaten-frame in which is journaled the platen-shaft 13 carrying the`platen 12 which may be rotated by the usual hand-wheel 14; or othermeans associated with the line-spacing or ratchet-wheel 15. i V

,Theprcsent invention includes a suitable frame arranged to be supportedso asi to be movable upon the ends of the carriageefraine by means ofbracket-.plates 17 and 18 which overlie the side pieces'lO and 11 of theplaten-frame alongside of the usual end plates Said bracket-plates havedepending side supports or webs 19 and 20, and are also formed at oneend with integral lugs 21, which are suitably pivoted on pins 22 carriedby ears 23 having flanges v24 secured by fasteners 25' upon thesidepieces 10 and 11 of thel platenframeshelf, incidental to typewritingmachines, is

The paperin which are trunn'ioned the pintles 32 ofv spools 33 havingguide-flangesv 34 and asso ciated in movement operativelyV with aratchet-wheel 35. Tlierotation of the spools, or either of them, takesplace against the tension of pressure plates 36 which are shown in theshape of spring arms 37 pressed yieldingly against the spools by meansof adjustable tensioning thuinb-screws 3S.

The auxiliary typewriter-ribbon 39 `is shown extending across the lengthof the Y platen and beyond the ends thereof, being operatively supportedand fed along in zigzag manner relatively to the platen by means new tobe described. The spools 33 are located in a plane at right angles tothe longitudinal axis of the platen, and in the course of feeding theopposing ends of they auxiliary ribbon off from or onto the spools, itbecomes necessary to divert and change the direction of movement of thisauxiliary ribbon, so that the intermediate portion thereof may bedisposed at right angles with respect to the direction of said spools,and thus occupy a position alongside of tliemain ribbon 28, as shown inthe drawings, but inasmuch as the intermediate portion of this ribbonhas to be offset to position one stretch` thereof in elevated relationwith respect Yto the other stretchthereof, it becomes necessary tochange the direction of n'ioveinent of the intermediate portion of thisauxiliary ribbon at another peint, between the endso'l the platen, atwhich point the vribbon takes a vertical direction of movement withrespect to the aforementioned' stretch, so that theY moment any point ofthe auxiliary ribbon 39 leaves either ofthe vspools 33 in its course ofmovement towards and upon the other spool, it changes its direction;thrice, and in each instance it has impressed thereon a Vribbon directlyfrom the spools 33, and is led therebeyond so as to be turned overanother roller 412, trunnioned upon an ear 43. also struck up from theweb 19 or 20. Brackets elet are secured by suitable fasteners upon thewebs 19 and 2O immediately above the the length of the platen'at theupper' plane thereof. Fixed ribbon-guides ai'e provided in. the shape ofplates 50- and 52 which aie disposed substantially perpendicularly withYrespect to the bracket-plates 17 and i8, so as to be located andextended across, below Yse and in front of said spools, as shownparticularly in Figures l and 2. The guide-plate 50 ismade longer thanthe guideplateV 52, so as to extend further down below thelatter andboth are formed with oppositely-inclining diagonal slots 5l and 53,respectively, one being spaced .below the other, the slot 5l of plate 50extending down below the slot 53 of the-plate 52. The auxiliary ribbon39,

after leaving the idlers or rollers 42, passes downwardly into thediagonal slots 51 and 53, undergoing a change in direction diagonally,as at the portions indicated 39, 35), respectively, so that they arepermitted to vassumel adistinctly horizontal direction of movement whichcauses the intermediate portion of this ribbon to move longitudinallyand horizontally across the platen.

The movable ribbon-guide has its upper portion arranged preferably inthe shape ofl Aa sleeve 5i, slida-bly engaging a rail or track 48secured by fastenersiett) vlongitudinally of the back `of the bar'i inspaced relation thereto. Depending from'the sleeve 5-1- is aplate 55extending downwardly to the lowerinost point of the plate 50 and formedwith a pair of vertically-separated diagonal slots57 and 58 which extendin the saine di- V rection, so that the upper slot 57 extends in thesaine direction and in horizontal alignment with the slot 53, fornied inthe plate 52, and so that the lower diagonal slot 58 extends intheopposite direction with re-A spect to and in horizontal alignment withthe diagonal slot 5l formed in the plate 50. The intermediate' portionof the auxiliary ribbon 39, atfthe points where it leaves the slots 51and 53 inthe plates 50'and 52, extends across the platen, entering one'of thediagonal slots 57 or 58, say slot 57, and movably project-ingtherethrough so as to be movable along the fi'ont surface of theguideplate The ribbon 39 is also arranged to 4iiiovably project throughthe other slot58,

so that this stretch 39h is disposed diagonally with respect to thelongitudinal axis of the platen, and moves in a vertical direction atthis point, and so that at one side of the pla'e55 the stretch 39 isdisposed horizontally, and at the other side .thereof .the stretch 39also extends horizontally, but is vertically spaced with respect to thestretch 39.

A handle 59 is secured upon the bar i6 by means of which this bar and'the pivotal frame carrying it may be lifted and swung upon-the Vpivots22, so that theauxiliary ribbon 39 may be moved out of contact with `theplaten l2, and thus provide clearance for -face of the bar lo and spacedinwardly 'from-the adjacent end. of the platen, this stop having a sidegage Giallowing one edge of thememorandum-sheet to engageit as toproperly space this sheet with respect .to therela'tivelywiderrecord-sheet A.

As an effective mean; for feeding along the superposed stretches of theauxiliary ribbon 39 so as to progressively presenta fresh surface ofsaid ribbon against the action of vthe type-bars 29, mechanismispiovided preferably controlled by the line-spacing n'iechanism ofthermachine for interiiiiltently unwindin'g the ribbonv oil' one yofthespools andv'inding Vit up onto the other spool. Suitably securedupon' the line-space slide 62 is a bracket-plate 68 secured thereto bymeans of a fastener (il, which plate (58 has an angular arm 65 which hasa lug 66, receiving the pivot-'pin (SS upon which is fulcrunied the pawl67 having ratchet-engaging point 6,9, this pawl being held yieldably ina horizontal position by means of a spring 70 which is secured iiXedlyupon a stud 7l. i

From the foregoing description, it will be seen that the movableribboi'i-guide-plate 55 is designed so as Ato slide upon the rail i8lengthwise of the platen, so as to be heldpsta.- tionary at any pointrelatively thereto by means of the thumb-screw 56. As this plate 55inoves'it always 'maintains two stretches of the ribbon 39 at' oppositesides thereof in perfect horizontal alignment, ythe distance it has beenadjusted with respect 'to either end of the platen determining. thevariable length of one of the stretches with respect to the 4otherstretch spacedfvertically therefrom,

which latter is illustrated by the inscription Dear sir indicated at I,or this guide-plate may beheldstationary at the other. extreme endoftheV platen, shown diagran'imatically at Figure 6, whereby the stretch39 of the 'auxiliary ribbon will be heldexactly at the printing line ofthe machine, allowing two sheets. of con'iparatively ,equall width toreceive simultaneously typed impressions, the outer sheet being typedthrough theinstru- 'mentality of the main ribbon 28, and the other sheetbeing typed through the instrumentality of the auxiliary ribbon 89interleaved between thetwo sheets. It will be seen that when themachineis to be used for another kind of work inv which the auxiliaryribbon is not required, said ribbon may Vbon is threaded with its tivohorizontal stretches 39 and 39 in a manner to be'positioned relativelyto. so as to be located be hind, the guide. The vertical stretch 391which joins the tivo horizontal stretches 89 and 39, and which have arelative motion, extends inv liront of the guide, thus avoiding` therubbing action o'l the ribbon against the Work-sheet. Y

The present invention linde immediate application in the typingotmonthly statements concerning;v which a record copy is made oit the sameentries Ona memorandumsheet inserted in the platen, such entries beingmade on the same date in the various Y statements. Such a typeofinaehine is described in Smith Patent No. 1,327,446, dated May 10,1921, in which 'form ot invention the ribbon-guide may be pern'ianentlyset in delinite position.

' After the' record-sheet A and memorandum-sheet B are inserted in theposition shown in Figure l, with one edge of the memorandumsheet Bengagingl the 'side gage 6l, and with its other end spaced ttorivardly'form the adjacent edge ot the' sheet A, whereby the marginal portion oi`sheet A is visible, the 'following typingv vaction may take place inthe preparation oit' monthly statements. Vil-hen the sheet- A has itsouter edge A disposed at the printing` line the marginal portionthereoit, which flanks the sheet B. is typed, through the instru-Vmentality ot themain ribbon 28, with the name-ef a lirm, say JamesSmith, as indicated at (It. Previously thereto the ribbonguide ispositioned so as to overlap the edge B ot' sheet P, so that the stretch39 extends completely across the Width oit sheet l atrprinting-lineposition, while the stretch 32) is held above stretch 39, so as toexpose the margin o't' sheet at the printing-line, in which last-nan'iedZone the inscription J ames Smith 7 is printed, Thetivo sheets A and Bare then successively line-spaced, line by line, and when the upper edgeE of the sheet B is Yin printing-line position the Vinscription or nameot the lirm John Doe is typed. as indicated at C, at which time thetype-bars 29, when the platen is brought to the proper point oppositethe margin o Vsheet A, eti-ect the typing', through the medium of themain ribbon 28, the saine name t John Doe upon the margmalportion otsheet A, as indicated at H, both inscriptions C and H beine', at thistime, in horizontal alignment and locatedat the printing line ol themachine. Any number of account entries may be typed along` the same linebetween inscriptions C and H against the main ribbon 28', so astio-produce impressions ot these entries upon sheetli, and reproduce thesame .impressions through the medium or stretch 39. of ribbon 39 uponthe record-sheet A'. such additional'entries heingdesignated broadly F.Similarly the two sheets are moved or `spaced the next line on theplaten l2, and now a: date, such as is indicated at in one lineI and Ein another line, is typed upon both sheets through the medium' otbothribbons toajether with inscriptions of entries F. By means ot thisarrangement, while the recordsheet n. is held stationary against theplaten, the memoraiulumfsheet B may be moved line by line, relativelythereto, may be necessary, so that any particular date and yaccountentries may be Vtyped siniultaneously upon vthe two sheets at any pointthereof along,` the printing line of the meehine opposite the nanieotthe lirm H, exposing to thevieiv et the typist the margin oi the sheet iheld stationary against the platen.r

it may be desirableto provide a. lever or 5 levers Y2, hilcrun'ied upona' stud 73, Vand carrying a roller or rollers le which engage the sheetsA and?) under tension at the upper plane olf the platen, so as to pressthese sheetsagainst the llat-ter, a vSuitable springer springs .75applying the tension against the rollers. By means ot this engagement oitheseV rollers, thersheet A is held stationary and againstlslipping,inthe paper-shelf 26 by means of the tension rollers lll when the lirontand rear pressure rollers To' and Y? are released it'rom Contact Viththe under side ol the platen, While the i sheet B, released by saidrollers 76 and 77,-is

removed troni the machine; it is also possible, in this manner, toinsert the sheet B without movin` sheet ii, although rollers 75 and T7are disengaged from the platen. Atteiboth sheets are yproperly mountedin position the proper rollers .76 and 77 re-engage with the platen tohold these sheets in the usual mriner, and then the roller 74 may bedisengaged in any suitable. manner (not shown). Since theribbon-guide-plate 55 is disposed intermediate the ends of the auXiliaryribben, said guide-plate serves as' a means to prevent the ribbon from'being dragged around the platen with the werke sheets when the platenis reversely rotated.
